AYes, the movie consists of scenes used in the original Japanese Digimon movies and in order to make it more appealing to Western audiences soundtrack was completely changed as well - the original music is all gone. Instead you hear English Rock/Pop songs or other new music creations. A detailed comparison, split in two parts, between the original Japanese versions and the US re-edit with pictures can be found here (Part 1) and here (Part 2).This of course created controversy. Specially in Latin America. The series with the Latinamerican dub always kept the original songs, while the movie used translated versions of the songs from the American dub.
